JOINT-TRIMMING MACHINE.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed February 14, 1919. Serial No. 276,940.

To all whom it may concern:

Be it known that I, J ULES G. LAURENTS, a citizen of the United States, and a resident of Lake Arthur, in the parish of Jefferson Davis and State of Louisiana, have made certain new and useful Improvements in J oint-Trimming Machines, of which the following is a specification.

My invention is an improvement in joint trimming machines, and has for its object to provide a machine of the character specified, capable of being controlled by hand, for trimming the joints in the decking and planking of wooden hull vessels.

In the drawings Figure 1 is a top plan view of the improved machine,

Figs. 2, 3, 4, and 5 are sections on the lines 2-2, 3-3, H, and 55, respectively, of Fig. 1.

In the present embodiment of the invention, a suitable supporting frame is provided in the form of a plate 1 of suitable width and length, the said plate having near-each end and on its upper face a handle 2 for convenience in manipulating the same. At each end, near one side edge, the plate is notched longitudinally as indicated at 3, and a guide disk 4 is arranged in each notch.

These guide disks are mounted upon j ournal pins 5, which are arranged eccentrically with respect to the disks, the said pins being held in openings in the plate, and in adjusted position by means of set screws 6 which are threaded through the plate into engagement with the pins. By loosening the-set screws 6, the journal pins with the disk may be turned to vary the height of the plate from the surface to be trimmed.

A cutter wheel 7 is arranged between the rollers 4:, the said wheel being secured to a shaft 8 which is journaled in a long bearing 9 on the plate. Referring to Fig. 4 it will be evident that the plate 1 is grooved transversely on its upper face at the bearing, and that the bearing is secured to the plate by means of screws 10 or the like, the shaft 8 running in the bearing and groove.

A flexible shaft indicated at 11 may be connected with the shaft 8 to operate the same from a suitable source of power, and the plate 1 has a guard 12 shaped to fit the upper portion of the wheel. This guard as shown in Fig. 2 covers the periphery of the wheel, and also the outer edge of the cutting face, and other handles 13 are provided on the guard for convenience in handling the cutter.

The shafts or journal pins 5 extend transversely of the plate 1 and by loosening the set screws 6, the guide disk may be adjusted laterally with respect to the plate, as well as turned angularly.

In operation the guides run in the seams between the planks, but lead and retain the cutter in the proper place, and they are adjustable for depth to permit of using on different thickness of planks, with as little change as possible, and they are also adjustable laterally with respect to the plate.

It will be understood that the cutting wheel may have depth on its rim or periphery, or it may be a plane circumferential saw.

I claim: 4

l. A device of the character specified, comprising a supporting plate having handles, and having near one side edge and at each end a longitudinally extending opening, a guide disk held in each opening, each disk being eccentrically mounted, and being adjustable angularly for the purpose specified, said plate having at the said side edge an upwardly extending guard, and a cutting wheel journaled on the plate and having its upper edge within the guard, said Wheel being adapted for connection with a suitable source of power to drive the same, and having its cutting-face outward.

2. A device of the character specified, comprising a supporting plate having handles, and having near one side edge and at each end a longitudinally extending opening, a guide disk held in each opening,

said plate having at the said side edge an upwardly extending guard, and a cutting wheel journaled on the plate and having its upper edge within the guard, said wheel being adapted for connection with a suitable source of power to drive the same, and having its cutting face outward.

3. A device of the character specified, comprising a supporting plate, disks connected to the plate at one edge on a connection eccentric to the disk and adjustable angularly for the purpose specified, and a cutting Wheel journaled on the plate beengularly for the purpose specified, and :1 tween the disks, said plate having a guard cutting Wheel journaled on the plate be- 10 covering the upper edge of the Wheel and tween the disks.
